A gorgeous spiritual successor to Supreme Commander with fun gameplay and great potential, though it remains unpolished with a clunky UI and optimization issues.

What players like

Spiritual successor to Supreme Commander: The game is widely recognized as a true spiritual successor to Supreme Commander and Total Annihilation, capturing the core gameplay, feel, and spirit of the originals. Many players note it plays exactly like Supreme Commander and scratches the itch left by the series.

Demo is enjoyable and promising: The demo is considered fun, solid, and extensive, giving a very positive impression and highlighting the game's great potential. It demonstrates the game well and has good replayability.

Game shows great potential: The game is seen as very promising with a strong foundation and many great ideas. Players believe it has the potential to become a fantastic game and one of the best RTS experiences.

Gameplay is fun and enjoyable: The core gameplay is described as fun, pleasant, and easy to enjoy. Players are having a good time with the game and find the gameplay experience to be positive.

Common complaints

Game is unpolished and unfinished: Reviewers note that the game feels like an early alpha with numerous bugs, rough edges, and missing features. The overall lack of polish detracts from the experience.

UI needs major overhaul: Players consistently report that the UI is unintuitive, cluttered, and hard to read, with small icons and poor readability. Many suggest a full redesign to improve clarity and usability.

Missing quality-of-life features: Players highlight the absence of essential QoL features such as hotkeys, control groups, patrol commands, and other shortcuts. These omissions hinder gameplay and are expected in the genre.

Gameplay and performance

Unit tiers and variety: Players appreciate the tiered unit system (T1-T4) and the variety of units and factions available. This adds strategic depth and replayability.

Classic RTS gameplay: The game is recognized as a real-time strategy title with classic RTS elements like base building, unit production, and resource management. This appeals to fans of the genre.

Survival mode available: A survival mode with waves of enemies is present, providing a solo challenge. Some mention multiple survival modes, adding variety.

Terrain alteration and destruction: The ability to alter terrain and destroy the map is a standout feature, with players mentioning destructible environments and nukes that change the landscape. This adds a dynamic element to battles.

Large-scale battles with many units: Players highlight the game's ability to support hundreds or thousands of units on the battlefield, emphasizing the epic scale of combat. This is a key positive feature.

Performance generally praised: Many reviewers report smooth performance, high frame rates, and good optimization across various systems, including older hardware and 4K resolutions. The game is often described as running without lag or stutter, with stable FPS in most scenarios.

Optimization issues reported: A significant number of reviewers mention the need for optimization, citing performance problems such as FPS drops, hitches, and high hardware utilization. These issues are often noted in specific scenarios like large unit counts or multiplayer.

Resolution locked at 320x200: Multiple reviewers report that the game launches or gets stuck at a very low resolution of 320x200, with no option to change it in the settings. This issue is often fixed only by switching to windowed mode and manually stretching the window, and it can reset when starting missions or opening settings.

Crashes and instability: Several reviewers experienced crashes, including during the demo, after the tutorial, or within 10-30 minutes of gameplay. Some crashes were severe enough to cause the whole PC to shut down or the GPU to overheat.

Performance issues with many units: Several reviewers note that performance degrades significantly when there are many units on the field, with FPS dropping to unplayable levels in some cases. This is a common concern for an RTS game, and reviewers hope for better optimization in large-scale battles.

Recommendations

Recommended for Supreme Commander fans: Multiple reviewers explicitly recommend this game to fans of Supreme Commander, Total Annihilation, and Forged Alliance, noting it captures the large-scale RTS feel. The game is seen as a worthy successor for those missing the grand RTS experience.
